If you are unable to connect to the internet, follow these steps:

  1. Update to the latest version of the BIMTech Tools application.
  2. Wait for the page to load completely.
  3. Check your proxy server settings if you are using one.

You can open the proxy server settings by clicking the Settings icon on the right side of the BIMTech Tools toolbar, or it will automatically appear if the internet connection fails.

In the Network Proxy Settings window, choose the Proxy Type:

  • Use system proxy settings: BIMTech Tools will load the system configuration.
  • Auto-detect: BIMTech Tools will try to automatically detect the proxy server settings, either system or by configuration script.
  • No proxy: If you have direct access to the internet.
  • Custom settings: For manual configuration, enter the proxy server address for HTTP(s)/SOCKS connection. In the Proxy server field, enter the URL or IP address of the proxy server, and in the Port field, enter the proxy server port number.


Please update BIMTech Tools to the latest version, check the internet connection, proxy server settings if used. New version is available here https://bimtech.cz/en/bimtech-tools-for-architects/

This issue may occur on older graphics cards, such as the AMD Radeon HD series, due to limited support for their drivers. Follow the steps below for possible solutions.

Switch to integrated graphics: If your computer has integrated graphics (such as Intel HD Graphics), you can switch to it.

  • In BIOS/UEFI: Restart your computer and enter the BIOS (usually by pressing Del, F2, or a similar key). In the graphics settings section, set the integrated graphics card as the primary one (IGPU).
  • In Windows: Go to Settings → System → Display → Graphics settings , select BIMTech Tools, and set "Integrated Graphics" as the preferred processor for rendering.

Replace the graphics card: If you do not have integrated graphics or its performance is insufficient, consider replacing the dedicated graphics card.

  • Older models, such as the AMD Radeon HD8490, may not have sufficient support for modern applications. Choose a newer graphics card model that better supports hardware acceleration and rendering.
  • When selecting a new card, make sure it is compatible with your motherboard and power supply.

If none of the options help, please feel free to contact us at support@bimtech.cz .

Please update to the latest version https://bimtech.cz/en/bimtech-tools-for-architects

Update to the latest version, which loads current data. In the Czech Republic, for exaple, this data is updated by source servers once a month. If boundaries still do not match, select a different drawing source in the layers and reinsert the map excerpt.

  1. Go to System Preferences .
  2. Select Security & Privacy .
  3. On the General tab, allow apps downloaded from the internet from unidentified developers.

Problem: In Revit 2021 and older versions, the terrain texture appears mirrored from below and is rotated.

Solution: Unfortunately, there is nothing that can be done directly in Revit to fix this issue. The only option is to adjust the texture in an external editor. Follow these steps:

  1. Open the texture in an external editor: Use a graphic editor such as Photoshop, GIMP, or another editor of your choice.
  2. Rotate the texture: Rotate the texture by 270 degrees.
  3. Vertically flip the texture: Use the vertical flip tool.
  4. Save the adjusted texture: Save the changes and use the adjusted texture in Revit.
